TILE I ABKEB.

Patented May 24, 1910.

.To all who-m 'it may concern:

Be it known that I, lVinniair it. Sirena, a citizen of the UnitedStates. :raiding at Denver, in the county of Dent er and State ofColorado, have invented certain new and useful Im rovements inTile-Markers; and I do here y declare the followingto a full, clear, andexact description of the -iu- -ventiom such as will enable othersskilled in of a tile cutting or marking instrument arthe cuttin handle.

`the invention2 ranged with an adjustable cutting blade adapted to becuredto the handle by any desired clamping means, as for instance abindin screw'.

A still further object in view is' the arrangement o a tool having asping lcutting blade formed with a su tantially pointed end, a cut-awayportion for rmittin the free discharge of the material cut, an acut-away ortion for admitting a clamping screw w ich 'is adapted toclamp the cutting blade to the handle, the cutaway portion through whichthe clamping screw passes being adapted to ermit the ready adjustment oftlie cutting lade as occasion mayrequire.

ith these and other ob]ects in view, the.

invention comprises certain novel construe tions, combinations andarrangement of parts as will be hereinafter more fully described andclaimed.

In the accompanying drawings: Figiire 1 is a perspective view of a tooembodying the` same Min shown in o ration. Fig. 2 is a longitu inalsection t ough the tool with the handle broken away. Fig. 3 is a detailperspective view of meirber removed from the i 4 is a section through atool embodying t e invention, approximately on line 4-4 of Fig. 2. Fig.5 is a section through Fig. 4, approximately on line 5 5.

errinr to the accompanyi drawin b numerals, 1 indicates the liigmdle ofgti e cutting or marking tool, and 2 the cuttin member holder.

15er 2 is provided with a flexible clamping The cutting member member 3which is firmly clamped against the cutting member 4 by any desiredmeans,

as for instance a screw 5. Screw is designed to pass loosely throughmember 3 and 30 member 4 and be threaded into holder 2 so that when thescrew is tightened the cutting p iember 4 will be tightly clamped inposiion.

Cutting, member 4 is preferably made 65 from spring material andpreferably formed of a single piece of metal bent upon itself in orderte forni a rounded end 6. Rounded end 6 is preferably sharpened at I toform a good cutting surface for cutting grooves 8 in a prepared surface9, which may be any desired material, as for instance, cement, plasterparis, or plaster. AThe cuttino' member 4 is cut away so as to form anan le at 10, and also is further cut away at 11 in order that the end 6ma be very short, and act substantially as if t e same was a point,though presenting a stron' er structure, by reason of the amount omaterial contained therein b the bevel or slant given the end of thetool y the cut away portions 10 and 11. Cut-away portion 11 especiallyis of im ortance as the same permits the easy disc .arge of the materialcut by cutt-in edge 7, and thus prevents any clogging, an consequentpoor cutting or marking of the instrument: The cutting member v4 may beof any desired length, and is formed at its reai'end with a notch 12 ineach side for permittingthe passage of screw 5. In forming the cuttingmember 4 of spring material the same is normally sli htly spnead whennot 1n the holder 2, so t at when positioned in holder 2 the same willnot drop vtherefrom even though not tightened by screw 5. In 98 order toproperly hold cutting member 4 in position i ing flanges 13 and 14 areprovided on older 2 which also ide clampingmember 3, as clearly seen inig. 5.

In operation when it is desired to use the 160 instrument a surface isprepared of any deslred material and the instrument is drawn thereover,guided 'if desired by a strai ht edge. Square blocks may be cut or anyot er sha e as desired for imitating Ygenuine tile, an the preparedsurface may be painted or stained either before or after the. cutting.

1. Ii an instrument ofthe class described,

a holder formed substantial] U-shaped in cross section, a cuttin mem `rfitted into the mlfler and extendmg therefrom in the holder.

^ 3. In an instrument of the class described, a holder provided at itsend with a flexible clamping member spaced apart from the holder, acutting member ositioned between the Hexible member and t 1e holder, andextending therefrom, and means for securin the cutting member betweenthe holder and the flexible member.

4. In an instrument of the class described, a holder formedsubstantially U-shaped in cross section, a flexible clamping membermovable toward the holder, a cutting member formed of flexible materialbent upon itself and carried by the flexible clamping mem ber, theexible cutting member having a slot having an offset arranged in thebevel, and a cutting point formed for cutting a predetermined shapedgroove.

6. In an instrument of the class described, a holder formedsubstantially channelshaped at one end, a clam ing member positionedupon the holder within the channel, a cutting member positioned betweenthe channel and the clampin member and projecting therefrom and ormed ofmaterlal bent upon itself, and means for securing the cutting member andthe clammng member to the channel portion of the hc der.

In testimon whereof I aix my signature in presence o two witnesses.
